Device for detecting fluid leakage

Abstract

The subject matter disclosed herein relates to fluid leakage detection. More particularly, subject matter relates to a device for detecting fluid leakage in a fluid drain pipe attached to a power transformer device. The device comprises fluid collection compartment attached to bottom of the fluid drain pipe and a fluid level switch is positioned in the fluid collection compartment to generate alarm signal to indicate fluid leakage.

The invention claimed is: 
     
       1. A device that detects leakage of fluid when a fluid drain valve or rupture disc disposed in a fluid drain pipe is closed, the device comprising:
 a fluid collection compartment attached to a bottom end of the fluid drain pipe that collects leaked fluid when the fluid drain valve or rupture disc is closed, the fluid collection compartment comprises:
 at least one through hole each at a top side and a bottom side of the fluid collection compartment, wherein the at least one through hole at the top side of the fluid collection compartment is connected to the bottom of the fluid drain pipe which has an extended diverging portion to channelize the leaked fluid into the fluid collection compartment; and 
 the bottom side of the fluid collection compartment is connected with a fluid discharge pipe that extends a predetermined height into the fluid collection compartment through the at least one through hole provided at the bottom side of the fluid collection compartment, wherein an area in the fluid collection compartment surrounding the fluid discharge pipe is configured as a fluid collection area to collect the leaked fluid when the fluid drain valve or rupture disc is closed; 
 
 at least one fluid level switch positioned at a predetermined location inside the fluid collection compartment to trigger an alarm upon collection of predetermined amount of the leaked fluid in the fluid collection area to indicate leakage of the fluid. 
 
     
     
       2. The device as claimed in  claim 1 , wherein the fluid collection compartment is provided with at least one drain plug that permits draining of the leaked fluid collected in the fluid collection area of the fluid collection compartment. 
     
     
       3. The device as claimed in  claim 1 , wherein the alarm is selected from at least one of an audio alarm and a visual alarm. 
     
     
       4. The device as claimed in  claim 1 , wherein the fluid drain valve or rupture disc is disposed outside of the fluid collection compartment. 
     
     
       5. A transformer explosion controlling system comprising the device as claimed in  claim 1 . 
     
     
       6. A transformer comprising the transformer explosion controlling system as claimed in  claim 5  that detects leakage of fluid when the fluid drain valve or rupture disc disposed in the fluid drain pipe is closed. 
     
     
       7. The device as claimed in  claim 1 , wherein a cutout is made on at least one side face of the fluid collection compartment. 
     
     
       8. The device as claimed in  claim 7 , further comprising a predetermined number of locking holes provided on a surrounding part of the cutout. 
     
     
       9. The device as claimed in  claim 8  further comprising at least one locking plate having a predetermined number of locking holes attached to a cutout side of the fluid collection compartment using fasteners with the help of locking holes provided on both the locking plate and the surrounding part of the cutout.
